7 18 Claims. (01. 176-3) My invention relates to apparatus forbasingeiectric incandescent lamps and similar devices.

One of the objects of my invention is to provide apparatus for properlypositioning the lead wires of a. lamp and then automatically feeding abase to locate it properly on the lamp in engagenient with said leadwires. The lamp and base are then transferred from the apparatuscomprising my invention to' other basing apparatus which causes the baseto be heated and thereby cemented to the'bulb of the lamp and alsosolders the said lead wires to the base. With the devices in use at thepresent time the services of several operators are required tostraighten the lead wires, thread one or more of the lead wires throughan aperture in the base and then place the lamp with its base in abasingmachine. Thesemanual operations are slow and costly and ,areeliminated by the apparatus comprising my '20 invention.

of a novel base feeding mechanism, one of the said lead wires beingthreaded through an aperture in the base. Means are provided fordefinitely positioning the base with respect to the lamp and to the saidlead wires. Means are also provided for removing a. lampfrom the head inwhich it is carried in case the base is not properly positioned thereon.Further features and advantages of my invention will appear from thefollowing detailed description of a species thereof. and from'thedrawings.

Referring to the drawings, the machine com,- prises a turret or carrier25 having a plurality of heads 26 mounted thereon at stations A to J in-25 elusive. The heads 26 are moved from station to station in acounter-clockwise direction by indexing movements of the turret 25caused by mechanism actuatedby a cam shaft 21 shown in Fig. 2. The camshaft 211s mounted below 30 the table 28 in the position of the dotdash'line 29 and, upon rotation, it causes the curved portion 30 of aface cam 3| to engage a roller 32 on wheel 33. With one revolution ofsaid cam 3|, the roller 32, which is one of a plurality on wheel 5 I3,is shifted sideward and said wheel 33 and turret 25, whichare bothfastened to shaft -34,

are indexed. The operating means for the cam shaft 21 is not shown, butit is preferably turned either by a basing machine located adjacent to40 the present machine or by a separate electric motor. During the firstindexing movements of the turret 25, the heads 26, which appear as inFigs. 3 and 5, pass through stations A, B, and Q, and 5 each receives alamp 35, placed therein by an operator. The lamp .35v is complete exceptfor a base ,and is shown herein of butt seal construc-' tion in whichleads 3i and I! thereof extend'outwardfrom opposite sides of' the lampneck II. 50 The lamps 35 are placed with the bulbous portion in a holder)9 with the neck 38 upstanding and one lead 36 above the V notch Ill ina post Ill. The post III is fastened to the holder 39 which is mountedon the body portion .ll of the I attached to an arm 41 which isconnected through a link 48 and suitable pins to a slide 49 located inways in body 4i. The position of the slide 49 and also the jaws 42 and43 is controlled by a track 58, which raises the slide 49 to a higherposition than shown when the jaws are open, through engagement with aroller 5| on a pin 52. A spring 53 which extends between a post on slide49 and an arm of body 4| causes the slide 49 to take the lower positionwhen track 50 is not engaged. The track 58 does not extend completelyaround the .turret but consists of a semi-circular segment located atthe various stations (A, B, C, I and J) at which the jaws 42 and 43 areheld open. The suction produced in the holder 39 for retaining the lamp35 therein is drawn through a passage 54 in the holder 39 and body 4|,which is connected through piping 55 to the top half 56 (Figs. 1 and 2)of a rotary valve. The piping 55 which is connected to each of the heads26 is also connected in each case to a separate passage in the upperhalf 56 of the rotary valve which is located over a groove 51 in thestationary lower half 58 (Fig. 2) of the rotary valve when the suctionis required.

With the lamp held securely, the lead straightening mechanism shown inFigs. 1 and 4 at station D operates upon it. This mechanism is providedfor purposes of gathering in and straightening the lead 31, which is tobe passed through an aperture in the end of the base, so that it isbrought within the operating range of the other mechanisms of themachine. The mechanism comprises jaws 60 and BI which are mounted onpins 62 and 63 extending from a slide 64 and which are first closed onthe lead 31 and then' moved outward away from the head 26. The closingmovement is produced by rotation of pins 62 and 63 which have gears 65and 66 respectively on the lower ends thereof which intermesh and whichare actuated by a gear segment 61 on pin 62 which is engaged by a rack68. The rack 88 slides in ways in block 89 which is attachedto theunderside of the slide 64 and is now moved backward by block 18. Theblock 18 is attached through link H and other apparatus not shown to theoperating apparatus of the mechanism at station E. The jaws 60 and 6!engage the lead 31 through blocks 12 and 13 respectively (Fig. 4') whichhave V-notched ends 12' which gather in the lead 31. Each of saidnotches 12' interlocks with a V-shaped boss 13 on the side of the otherjaw. The blocks 12 and 13 close on the lead 31 until they grip itslightly whereupon further backward movement of the rack 68 overcomesthe friction produced by the block 14 against the ways of standard 15and the slide 64 and 'jaws' 60 and 6| are moved back. The block 14 ispressed against the ways in thestandard 15 by a spring 16 located in awell in slide 64 which is retained within the ways of said standard byplates 11 and 18. The backward movement of the jaws 68 and SI incombination with the flame from a 2,120,877 head as which in turn ismounted on the turret burner 19 serves to straighten the lead 31. Theburner 19 is supplied with gas from a pipe 88 which is mounted on a post8| extending upward from slide 64 and is moved back therewith. Duringthe movement, the blocks 12 and 13 pass off the end of the lead 31.Before another lead 31 from a succeeding lamp 35 is operated on, rack 68is moved forward, causing the jaws 60 and 6! to swing open and the slide64 to be advanced. The movement of the slide 64 follows the opening ofthe jaws because of the friction produced by block 14. When the jaws 60and GI have opened suificiently, the block 10 strikes the slide 64 andit is moved positively.

The" lamp 35 is indexed from station 1) to E. At station E, the leads 36and 31 are bent so that a base can be placed on the neck 38 of the lamp35 and so that the leads 36 and 31, with'the base in place, will beproperly positioned with respect thereto. When the lamp 35 is firstplaced in the machine, the leads 36 and 31 extend laterally outward fromthe neck 38. The said leads are engaged by fingers 83, 84 and 85respectively (Figs. 5 and 6). The fingers 83 and 84 are attached to a,vertical sub-slide 86 which is mounted in a slide 81 in the ways ofstandard 88 and which is connected thereto through a spring 89 and posts96 and SI in slide 81 and sub-slide 86 respectively. The slide 81 ismoved down to bring the V-notched end of the finger 83 against lead 36and bend it downward so that it is adjacent the bulbous portion of thelamp 35 which will later contact the rim of the base. The outer end ofthe lead 36 passes into the V notch in the post 40 and is engaged byfinger 84 which bends it downward out of the way. When this point isreached, the end of finger 83 strikes the shoulder 4| on the post 40 andthe over-travel of slide 81 causes the sub-slide 86 to be shifted in itsways in the slide 81 and the spring 89 to be stretched. Post 90 moves ina'slot in the subslide 86 during this interval.

The finger 85 first moves upward from the positidn shown in dotted lines(Fig. 5) and then swings inward and upward to the position shown in fulllines. The lead 31 is moved to the position shown which moves it out ofthe way of the base and causes it to be threaded through the endaperture therein when the base is dropped into cam slot 94, a. studextending from said standard 88. Movement of the arm 92 is produced byan arm 96 which is connected thereto through pin 91 and is controlled bythe travel of stud 95 in the cam slot 94. The arm 98 is attached to ashaft 88 which is rotatively mounted in standard 88 and is operated by alever 99 and rod I80 from mechanism shown in Fig. 2. Shaft 88 alsooperates the slide 81 through arm ifll, link I02, lever I83 and linkI84. Lever I 03 turnsabout a stud I85 extending from the standard 88.The operating mechanism for rod I08, as shown in Fig. 2, comprises alever I86 which is pivoted on shaft I01 and engages, through roller I08,the slot of the face or box cam I 88 on shaft 21.

Indexing the heads 26 into station F places the lamp 85 inoperative-relation to themechanism shown in Figs. 7, 8, and 9 whichfurther straightens out and sets the upper end of lead 31 so that itwill not catch on the base when said base is dropped onto the lamp 35.The mechanism comprises jaws-III and III which close on lead 81 at apoint just above the lamp :5, and j'aws m and m which close on said.lead 31-atapoint just above the flrst'pair or laws H and III. The jawsIIO and III are mounted on levers H4 and 5 respectively which aremounted on pins I-I I5 extending between a standard I" and a'plate II8.Said levers II4 I and H5 are actuated by a slide cam I I5 which getherby the pin I21 and are actuated through engages rollers I20-I20 mountedin the arms of levers [I4 and II5. The slide cam H9 is mounted in waysin standard H1 in which it is held by plate H8 and is. raised when thejaws H0 and III are to be closed sothat it is moved from engagement withthe rollers I20I20. The levers H4 and H5 are moved in by a spring I2Iwhich extends between posts in .each lever and are caused to take acentral position over the head 26 located at that position by stopscrews I22--I22 thereon which strike blocks I23-I23 mounted on standardII1. Jaws H2 and H3 are mounted on levers I24 and I25 respectively andare closed by the toggle arrangement afiorded by a rod I26 which isconnected through pin I21 and links I28, I29 to the ends of said levers.To the top of jaw H2 is fastened a notched guide I30 which directs thelead 31 to the center of the jaws H2 and H3. The levers I24 and I25 arepivotally mounted on a pin I3I which is located in the lower part of aslot I32 in the standardlfl and plate H8 .and which engages standard II1through a spring I33 and washer I34 and engages plate II8 through itshead I35.

The spring I33 is held in compression by a nut I35 on the pin I3I andcauses washer I34 and the headl35 to engage the standard H1 and plate II8 respectively with sufficient friction to hold the jaws H2 and H3 inposition while they are closed quite tightly. After being closed, thejaws H2 and H3 are pulled upward to the very end of the lead 31 which isthereby straightened and slightly stretched. This movement and the heatfromthe flame of a burner I31, which is directed onto the lead 31, causeit to be permanently set. The upward movement is produced by thecontinued upward movement of rod I26 after the jaws H2 and H3 haveclosed and results in the pin I'3l shifting to a higher position in slotI32. The tightness with which the jaws H2 and H3 close on the lead 31 iscontrolled by the extent to whichthe spring I33 is compressed. Rod I25and slide cam II9 are connected toa link I 38, lever I39 and rod I40which is connected to operating mechanism located below the table 28andshown in Fig. 2. The lever I39 turns about a pin I4I extending fromstandard I I1. The operating mechanism comprises a box or face cam I42which is mounted on cam shaft of said cam I42 through 21, and a leverI43 which engages the ways a roller I44 and which is connected to therod I40. 1

At the next station G a base I45, which is selected from a pile inahopper I45, is automatically placed in an inverted position andproperly orientated with respect to the lamp 35 in the head 25. As shownin Figs. 10 and 11, the bases I45 are piled in the circular hopper I45and are selected for feeding by means of a notched wheel 441 located onthe bottom thereof which is turned so that the bases I45 are agitatedand finally fall into the notches I48 in the periphery of said wheelI41. The wheel I41 is mounted on a boss I49 extending from the bottomI50 of the hopper is indexed in a counter-clockwise direction byapparatus including a pawl I52 and a lever I53 which is pivoted on a pinI54 extending from the bottom I50 0! the hopper I45. The pawl I52 ispivoted on a pin I55 extending from lever I53 and is caused to engagethe notches I48 of the wheel I41 by a spring I55. Movement of the pawlI52 and lever I 53 is brought about by a mechanical linkage comprising arod I51, a lever I58 which is pivoted on an arm I59 extending from thehopper bottom I50, a rod I50, a lever I5I which is pivoted on pin I52extending from a bracket I53 on the lower-part of the table 28, a linkI54 and a lever I55 (Fig. 2) which engages, through a roller I55, a camI61 on cam shaft 21. The roller I55 is caused to follow the cam I51 by aspring I68 which is located between lever -I55 and the table 28. A

roller I66 on a lever I10 is provided to hold the wheel I41 in positionbetween indexing movements. The roller I59 is mounted on the free end orthe lever I10 which is pivoted on a pin l1I extending from a bracket I12on the hopper bottom I50 and is held in position by a spring I13 whichis located between posts extending from the bracket I12 and said leverI10.

The indexing movement of the wheel I41 causes each of the notches I48therein to be carried under the pile of bases I45 at the lower end ofthe hopper I45, said bases being shifted about and finally falling intomost of said notches I48. The bases I45 are greatly overweighted at oneend because of the glass insulating plug I14 therein and generally fallinto the notches I48 with the plug I14 lowermost. Each notch I48 isslightly larger than the diameter of thecomplete base I45 and holds saidbase I45 in either an upright or an inverted position. The rotation ofthe wheel I41 carries the notches I48 under a partition I15 which pushesoff any extra bases I45 that may have been caught on said wheel I41 andcarried up out of the pile with it. After passing under the partitionI15, the base I45 in.

each notch I48 comes into engagement with a stationary finger I16 whichwipes the side of the base. I45 in order -to rotate it slightly (about45) should the base I45 be lying with its bayonet pins I11 substantiallylengthwise in the notch I48. The finger I15 catches the outermost pinThe slide I11 lies in ways in the bottom section I50 0! the hopper I45in which it is retained by a 7 plate I and is can'ied against the baseI45 by the contraction of a spring I8I which is located between posts inthe slide I11 and the plate I80. A slot in the outer end of the slideI11 is engaged by a pin I82 in lever I83 which controls the movement ofsaid slide I11 by turning about a pin on bracket I84 which extends fromthe hopper bottom I50. The lever I83 is' operated by the bracket I85(Figs. 10 and 12) whichfis clamped directly to pin I18 and which engagessaid lever I83 through a rod I85 and collar I81. The bracket I85 ismounted on apin I88 in the end or a lever III which in turn is pivotedon a pin 190 in the hopper bottom I50 and which forms one section of anoperating linkage consisting of rod I9I, lever I92 which pivots on pinI62, link I93 and lever I94 which engages the cam I95 on the cam shaft21 through roller I96. The base I45 is released after the pin I18 hasbeen moved upward to the position shown in Fig. 12 and then loweredagain.

The next indexing movement of the wheel I41 I carries the base I 45 intoposition above a plunger I91 which is moved upward to push the base I45upward out of the wheel 'I41 through a die I98 and into an arcuatechannel I99 (see Fig. 10) in bracket 200. The plunger I91 is attached toa block 201 which is mounted between sections of lever I89 on the pinI83 and is slotted for said pin I88 so'that a spring 202 is required tohold said block 201 in position on the pin I88. The spring 202 isattached to posts in lever I89 and the block 201 and allows the pin I88to move upward in the slot in block 20I when the plunger I91 is unableto push a base I45 upward. The resiliency of the spring 202 is such thatbases I45 which do not register properly with the aperture in die I98due to distortion, improper registration, imperfections, etc., are notforced into said die I98 but fall back into a notch M8 in wheel I41. Ifthe base I45 is in an inverted position,

.the plunger I91 enters the interior thereof and does not raise itsufliciently for it to enter the die I98. The inverted base I 45 iscarried with the wheel I41 for two more indexing periods whereupon it isejected by a plunger 203. Plunger 203 is fastened to a block 204 whichpivots on pin I68 and is actuated by movement thereof. To compensate forthe failure of the bases I45 to fill all of the notches I48 in wheel I41and to always enter said notches I48 right side up, the wheel I41,thepin'l18 and the plungers I91 and 203 are operated twice as fast asthe rest of the machine by the cams I61 and I95.

The bases I45 pushed into the die I98 (shown inverted in Fig. 13) arefirst fed into a round opening therein designed to prevent oversize anddistorted bases I45 from passing. The pins I 11 of said bases I45 engagethe inclined surfaces 205 of a transverse V-shaped notch intersectingthe round aperture in said die I98 which causes the bases I45 to berotated and directs the pins I11 into grooves 206 in opposite sides ofthe round aperture. The die I98 is fastened to a portion of the hopperbottom I50 and, having properly orientated the bases I45, allows them toenter the channel I99 of the bracket 200. The chan- The air jet alsoblowsout through a hole. (not shown) in the bottom of the channel I 99all particles of insulation from the bases I45, etc., which might hindermovement thereof in the said channel. 'There is a hole in the bracket200 below the feeler 2I2 which is periodically carried down into contactwith a base I45 located adjacent thereto or to an even lower position ifa base I45 does not occupy this position. The feeler 2I2 push rod 2I5is, as shown in Fig. 12, attached by nel I99 is provided with a groovefor one of the base pins I11 and is entered by a friction pin 201 (Fig.11) which prevents the lowermost base I45 from falling back down throughthe die I98. The friction pin 201 is attached to a spring leaf 208 (Fig.10) which is attached to bracket 200 and which presses said pin 201against the base I45. Succeeding bases I45 inserted in the end of thechannel I99 force the bases I 45 already therein upward around thecircular portion thereof (Fig.

10) until they are struck by the air jet issuing means of block 2I6 topin I88 which causes it to reciprocate. The end of lever 2I3 is kept incontact with the upper end of the push rod 2 I by a spring 2" whichextends between the said lever 2I3 and bracket 200. Said end of the pushrod 2I5 is held in position by 2. lug 2I8 (Fig. 14) extending frombracket 200. When raised above the bases I45 or resting upon a base I45,the feeler 2I2 holds the lever 2I3 in a position which causes theindexing movement of the wheel I41 to stop and so prevents theintroduction of more bases I 45 into the channel I99. The lever 2I3(Fig. is attached through a link 2I9- to a lever 220 which turns a shaftH9. The shaft 2I9 is fastened to arm 220 .(Fig. 11) which turns a catch22I about the pin 222 extending from the hopper bottom I50 so that itmoves to a position in front of the pin I55 of the indexing mechanismfor the wheel I41 on the back stroke and prevents further movementthereof. The catch HI and arm 220' are shown in Figs. 1 and 11 in thefeeding position whereas lever 2I3 in Fig. 10 is in the non-feedingposition. The weight of the upper end of the catch 22I swings it out ofposition when lever 2I3 and arm 220' are moved to the non-feedingposition so that the indexing mechanism is again allowed to operate.

The bases I 45 pass down the forward part of the channel I99 in bracket200 by gravity and are finally engaged by the block 225 (Fig. 16) of anescapement mechanism. The block 225 is.

pushed against the end base'I45 in the channel I99,.so as to prevent itfrom moving, by a lever 226 which is pivoted on a pin 221 extending frombracket 200 and which is held in this position by a spring 228 extendingbetween posts in said lever 226 and the bracket'200. The release of thebases I45 is caused by aclockwlse movement of lever 226 and is broughtabout by engagement of a bolt 229 in a lever 230 with the horizontal armof said lever 226. The lever 230 pivots on a pin 23I (Fig. 14) extendingfrom bracket 200 and is operated by rod 232 (Figs; 2 and 10) from alever 233 which engages the ways of earn 234 through roller 235. Thebase I45 released by the escapement mechanism drops down between jaws236 and 231 and comes to rest on the projecting portions 238 thereof.The jaws 236 and 231 are so positioned with respect to. the end of thechannel I99 in bracket 200 that only one base I45 escapes therefrom andthe succeeding base I45 takes a position before the escapementmechanism. The jaws 236 and 231'are pivoted on pins 239 and 240 on aslide 24I which is located 10) which in turn engages, through roller241, a

cam 248 on cam shaft 21. The ends of the jaws 236 and 231 extend into achannel 249 in the slide 2 and are held open at this position by a'cam253 which is located between a roller 25.I pivotally attached to each ofsaid jaws. The jaws 235 and 231. are. opened simultaneously with the op-5 eration o! the -escapem'ent means since the cam 253 is attached to aslide 252 which is connected by link 253 to lever 233 and is moveddownwardtherewith. The slide 252 is mounted in ways in bracket 255 inwhich it .is held by plates 254 and 255. When the escapement mechanismis closed on the next to the last base I45, the slide 252, and cam 255are moved upward and the jaws 235 and 231 are pulled together so as togrip the end base I45 located therebetween, by the contraction of aspring 253 (Fig. 14) which is located between posts in the said jaws 235and 231. Should the bases I45 not advance to the escapement mechanismfor any reason, the lever, 223 will swingiurtherintolthe channel I33 andan electric alarm circuit be closed. The circult includes a pair ofcontacts (not shown), one of which is mounted-on an insulating am 251(Fig-'14) and connected towire 253, and the otheroi whichis'mounted onan am 259 extend-' v ingi'rom bracketl 233 and attached to wire 253'.The warning light other parts 0! the alarm system-are not :shown.

The roller 5| engages the arm 211 'only whenit is below its normal position due to the fact that the jaws 42 and 43of the head 25 have closed further, than is normally allowed by the neck33 of a lamp 35. Once thebasel45 is deposited on the arms 254 and 255-of jaws 255 and 25I respectively, the slide 24I moves upward again foranother base I45 and the said arms 254' and 255 are separated, leavingthe base I45 to drop down onto the plates 44 and 45 of the jaws 42and43.

of the head 25. The jaws 255 and 25l are opened by engagement of therollers 253 thereon with opposite sides'of the cam 252. The turret 25 isnow indexed. i

' At position H,"the base I45 is lifted from the plates 44 and 45 ofthejaws 42 and 43' or the turret 25, adjusted angularly to correct anymis-. alignment; notched and, after; said jaws 42 and 43 areopened, isplaced over the end 0! the lamp .35 in-the position it is to beattachedthereto.

The notching operation consists, as shown in- Figs. 17 and 18, inputtinga small notch in the rim of the shell 235 'of the base I45 so that thesideward projecting lead 35 will fall thereinto and permit the-rim ofthe base shell 235 to seat firmly against'the bulb of the lamp 35. Thebase I45 is taken from its position on the plates 44 and 45 by jaws 23Iand 232 which are so shaped as to engage the sides of the base pins I11if the baseI45 is turned out of its correct angular position and totu'rnsaid base I45 back into position.- The jaws 23I and 232 areattached to levers 233 and 234 respectively, each of which Y is mountedon a pin 235 extending from a. slide 235. The outer ends of the pins235-P235 are connected together by a block 231. The levers 233 and 234are operated by a toggle system com prising links233-and 239 and a sliderod 295, the

latter of which is mounted in ways in slide 235 andis operated jointlyby a lever 29I and spring 292. The jaws 23I and 232 are closed by aclockwise movement of lever 29! about a pin 293 to carry a pin 294 downfrom the upper end of a slot 295 in the slide rod 295. The spring 292,which is located between posts in slide 235 and the slide rod 295, thencontracts and the jaws 233 and 234.

close as the slide rod 295 moves down. The pin 293 is mounted on astandard 295 and supports the lever 29I which is operated through rod291 from cam 293 and lever 299 (Fig. 2). The lever 299 is mounted onshaft I51 and engages a box or side cam 293 through roller 355. Havinggripped the base I45, the jaws -23I and 282 move upward until said baseI is some distance above the head 25and slightly above the notchingmechanism-.- The upward movement is brought about by a similar movementof slide 235 which is slid in its ways in standard 295 by lever 35L Thelever 35I engages theslide 235 through alink 352 and pin 353 and isturned about the pin 334 extending from standard 295. A slot in thestandard 295 behind the slide 235 is provided for the rearward extendingportion of pin 353. Lever 35I is actuatedby rod 355 which is alsoconnected to the lever 355 -(liig. 2) which engages cam 351 throughroller 353. Thelever 355 turns about the shaft I51.

The notching mechanism shown in Figs. l'l and 18 -is'n0w moved under thebase I45 which is'lowered until the rim of the base shell 235 rests in agroove 359 in the slidably mounted die 3 I3, as shown in Fig. 17. Thedie 3I3 is mounted in ways in standard 296 in which it isheld by plate3| I and is actuated through pin 3I2 by lever 3I3, link 3 and arm 3| 5.During the forward movement of the die 3|3, the lever 3I3 does not turnabout either pin 3|2 or 3|6 and the sub-slide 3, which rides on die 3I3and in ways in the standard 296 and which supports pin 3I6, remainsstationary therein. The position of the sub-slide 3|! is fixed by theengagement of a notching blade 3I8, which is attached to said sub-slide3!! and is located in a slot 3I9 in the die 3I3, with a block 323 whichis located in a transverse channel in said die 3I3. The blade 3I3 iskept in contact with the block 323 by a spring 32I, a portion of whichis located within a well in the die 3|3, and which engages an arm 322extending from the sub-slide 3". When the die 3I3 is properly locatedbelow the base I45, the pin 3|2, which extends through said die 3|3 intoa slot (not shown) in the standard 296, strikes the end of said. slot. Arest period now occurs in the movement of arm 3I5 while the base shell233 is lowered into the groove 339 whereupon the arm 3I5 again moves andthe notching blade 3|3 is caused to strike and punch a small notch inthe shell 233. The blade 3|8 is actuated through the lever 3I3 whichpivots on pin 3I2 and, acting through pin 3I6, advances the sub-slide3". The arm 3I5 which actuates these parts is mounted on a pin 323 whichpasses through the standard 296 and is attached to arm 324. The arm 324is actuated through a rod 325 which, as shown in Fig. 2, is connected tolever 326 which engages a cam 32! through roller 323. The lever 326turns on shaft |3!.

After the base I45 is notched, it is raised by the jaws 23I and 282 andthe die 3I3 and subslide 3|! are moved back. During this interval, thejaws 42 and 43 of the turret head 26 swing outward away from the neck 33of the lamp 35, leaving it in an upright position on the head 26. Thejaws 42 and 43 are opened by a downward movement of roller 5| which atthis position rides on a block 329 (Fig. 2) on the end of rod 333instead of on track 53. The rod 333 is held in po-- sition by the table23 and is moved by arm 33I which is fastened to and moved by the shaft332 which is mounted on the under side of the table 23 and is turned byarm 333. The arm 333 is actuated by a lever 334 which is connectedthereto through a link 335 and which engages a cam 336 on cam shaft 2!through roller 331. The base I45 is now moved down over the upstandinglead 3! and the neck 38 of the lamp 35 and, when in contact with thebulb, is released. The upstanding lead 3! passes through the centeropening in the insulating plug "4 of the base I45 and the sidewardprojecting lead 36 enters the notch cut in the rim of the base shell233. Before the head 26 is indexed to the next position, the

jaws 42 and 43 are closed, this time engaging the base I45 and holdingit in position.

With the next indexing movement of the head 26, the roller 5| thereofleaves the block 329, and the jaws 42 and 43 close on the base I45.Midway between stations H and I the roller 5| contacts the end of lever363 (Fig. 2) and, upon reaching station I, rides on the end of track 53which causes the jaws 42 'and 43 to open. At station I, thehead 26 islocated before a mechanism which operates only to remove the lamp 35when it does. not carry a base I45. Normally, the base I45 rests on thelamp 35 and, until roller 5| reaches track 53, is gripped by the jaws 42and 43. However, in case a base I45 is not presto be lowered intoengagement "with the lamp 35 when the head 26 reaches station I. Shoulda base I 45 be hanging on the end of lead 3! in a position above jaws 42and 43, it is struck by a plate 343 which is attached to jaw 339 and isswept sideward into a box (not shown) atthe side of the turret 25. Thejaws 333 and 339 are mounted on arms 3 and 342 respectively which arefastened to pins 343 and 344 respectively. The pins 343 and 344 arepivoted in a bracket 345 and are attachedto the intermeshing gears 346and 34! respectively. The bracket 345 is attached to a vertical shaft343 which, as shown in Fig. 2, has a pair of collars thereon engagingtherebetween the end of a pin 349 in a lever 353. The shaft 343 iss'lidably mounted in the bracket 35I and causes the jaws 333 and 339 tomove as described when it is moved up and down by the lever 353 whichengages cam 352 through roller 353. The first part of the downwardmovement of the shaft 343 turns the jaws 333 and 339 to a position abovethe head", dueto the fact that a roller 354 (Fig. 19), which is attachedto said shaft 348, then travels in the diagonal portion of the slot 355in the bracket 35I and causes said shaft 343 to turn. Further downwardmovement of the shaft 348 causes the 'jaws 333 and 339 to.

contact the lamp 35 and to be pushed open thereby. The jaws 333 and 339are pulled toward each other by a spring 356 which is located betweenposts in arms 3 and 342 and which causes said jaws 338 and 339 to gripthe lamp 35 after they have passed over the bulb thereof. Shoulders onthe arms '3 and 342 adjacent the pins 343 and 344 prevent the jaws 338and 339 from closing completely when a lamp 35 is not in positiontherebetween. The return upward and turning movement of the jaws 333 and339 carries the lamp 35 over a container (not shown) and carside oflever 353 lies in the notch. in latch 359 and is caught thereby. Thelatch 359 is attached to a pin extending from the bottom of the table 26and supports lever 353 so that roller 353 cannot follow the contour ofcam 352. Operation of the mechanism occurs when the roller 5| oi. theturret head 26 lies in the lower position already described and engagesthe lever 363 which turns about the stationary pin on which it ismounted. The other end of lever 363 is connected through link 36! andarm 362 to the latch 359 which is swung out of engagement with pin 349when a baseless lamp comes to position I.

The lamp 35 and base I45 are unloaded from my machine and are placed ina basing machine which is located adjacent .thereto and which ispreferably of the typeshown in Patent 1,708,756, J. T. Fagan et al.,issued April 9, 1929. The basing machine comprises a plurality of headswhich are indexed along line 363 (Fig. 1) and which refor this transferis shown in Figs. 1, 20 and 21,

and is provided with separate pairs of jaws 364-364 and 365465 forengaging the leads 36 and 31, respectively, at points adjacent the baseI45. The object of this particular construction is to eliminate the needfor changes in the transferring mechanism when the machine is made tooperate'with other types and sizes of lamps. The jaws 36 l--364 are eachfastened to an arm 366 by means of a screw 365' and a spring 366' whichtogether allow a certain amount of movement of the arm 366 after thejaws 364, engage the lead 36. The jaws 365- 365 are each fasteneddirectly to one of said arms 366 and they engage and grip lead 31 duringthe movement of jaws 364-364 which compresses the springs 366'. The

jaws 365-365 are the principal means of supp rt for the lamp 35 and baseI45, the other jaws 365 preventing the assembly from turning out ofposition. Should the jaws 365 fail to engage lead 31,

the lamp 35 will not be removed as the springs 366'--366' are not ofsufllcient strength to cause jaws 364 to grip and support said lamp. The

ment. of the jaws is caused by a similar movement of the transfer arm 3"which is attached to the upper end of a sleeve 312. The sleeve 312 isslidably mounted in bracket 313, and is moved vertically, asshown inFig. 2, by mechanism engaging collars-314 on the lower end thereof. Thesaid mechanism comprises an arm 315 which engages thercollars 314through roller 316, an arm 311 which is connected to arm 315 throughshaft 316, a rod 313 which connects arm 311 to lever 366, and a doubleface cam 36I which is engaged by aroller 362 in the end of lever 366.The lever 366 is-turned about shaft I61 and is operated throughengagement of the roller 362 with the ways (not shown) in the far sideof the cam 36I.

As the transfer jaws are moved down into position, a shoe 363 (Fig. 21)strikes the top of the base I45 pushing it firmly against the lamp 35.

The shoe 383 is attached to a stud 364, one end of which is located inthe end of a tube 365 ex tending from head 366, and which is presseddownward by a spring 366 in said tube. The shoe 383 holds the base I45in position during the transferring operation and is supported, when notagainst-a base I45, by a pin (not shown) located in stud 384 and in aslot in tube 365. With the transfer jaws in the pick-up position, a stud361 extending from the head 366 is against a stud 386 extending from arm31I. Closing of the jaws swung so as to place said lamp 35 and said baseI45 in a head of the basing machine at position K. The arm 3" is swungby rotation of a gear .332 which is provided with a tubular portion 333extending through the lower part of bracket 313 and connected througharm 334, bar 335 and arm 336 to tube 312. The arm 334 is attached to thetubular portion 333 of gear 332 whereas the arm 336 is attached to tube312. This construction allows the transferring arm 3H and the tube 312to be raised and lowered without disconnecting the rotating mechanismsince arm 336 slides along the bar 335. The gear 332 is rotated by arack 331 which is supported by a bracket 336 extending from bracket 313.The rack 331 is connected through rod 333 to arm 466 (Fig. 2) which ismounted on shaft 46I which in turn is operated through arm 462, bar 463and the lever 464. The lever 464 is pivoted on shaft I61 and engagesways in cam 36I through roller 465. During the transferring movement ofthe arm 3", the lamp 35 and base I45 are turned slightly sothat they arenearly correctly positioned when reaching the basing machine. Thisadjustment is provided by holding the head 366 in one position duringthis movement and is provided by the gradual rotation of shaft 316 whichactuates said head through arm 363, link 336 and one of the arms 366.The.

shaft-316 is provided with a gear 466 on its upper end which meshes witha rack 461 lying in the ways in arm 3". The rack 461 also meshes with agear 466 on the end of a post 463 located in the center of sleeve 312and is moved longitudinally the required amount by the turning movementof the arm 31I as the gear 466 is held stationary.

In this instance, the transfer arm 31I is raised a short distance whileat position K to place the end lead 31 and the insulating plug I14properly in the mechanism of the basing machine. This movement isaccomplished through sleeve 312 by mechanism already described. Properorientation of the base I45 and lamp 35 now takes place. The base I45and lamp 3.5 are turned to their proper position by rotation ofthetransfer head 366, through movement of rack 461, until stud 361 thereofstrikes stud H6. The rack 461 is now moved by rotation of gear 468 andpost 463, the latter of which, as shown in Fig. 2. is turned by -arm 4which is connected through rod M2 to arm 4I3 which in turn is connectedthrough shaft 4I4, arm M5 and bar 4I6-to lever M1. The lever 4" isturned about shaft I61. by cam 4I6 which it engages through roller 3.After the rotation of the transfer head 366 is stopped. the rack 461continues to move, causing shaft 316 to be turned separately and thejaws 364 and 365 to be opened. thereby releasing the lamp 35 and baseI45.

' Should a lamp 35 still remain in the turret head 26. after operationof the transfer mechanism, it is blown out at a point midway betweenstations J and A by a blast of air from pipe 426 as the turret 25 isindexed. The vacuum normally drawing on thelamp 35 and holding it inposition in the head 26 is cut 011? by the rotary valve 56-51 at thispoint so that thelamp is easily removed.
